alright so heres my newest problem, its hard to explain and might sound weird but bare with me...when i take off from a stop just normal everything runs fine, but if im at a stop and i try to punch and get on it i feel a vigorous sort of thump from under the car towards the back, almost feels like im running something over, car is still driveable though. if anyone has any idea on what this may be please let me know. thanks in advance

 

Sounds like your tranny mount is starting to separate. They are cheap and easy to replace. You need to go under the car and look. Here's one from Advance Auto http://shop.advanceautoparts.com/web...rm=trans+mount
